gr-qc papers | Gist.Science

Quantum gravity represents the frontier where the very large meets the very small, attempting to unify Einstein's theory of gravity with the strange rules of quantum mechanics. This field explores the fundamental fabric of spacetime, seeking to understand how the universe behaves at its most extreme scales, from the heart of black holes to the moment of the Big Bang. Because these concepts often involve complex mathematics, they can feel distant to non-specialists, yet they hold the key to a complete picture of physical reality.

At Gist.Science, we bridge this gap by processing every new preprint in this category directly from arXiv. Our team provides both plain-language explanations and detailed technical summaries for each paper, ensuring that groundbreaking research is accessible to everyone, from curious students to seasoned researchers. Below are the latest papers in quantum gravity, offering fresh insights into the nature of our cosmos.

Bosonic and fermionic mutual information of N-partite systems in dilaton black hole background

This study analytically investigates how the Hawking effect in a GHS dilaton black hole background influences the N-partite mutual information and relative entropy of coherence for bosonic and fermionic GHZ and W states, revealing that fermionic mutual information exceeds bosonic mutual information while the opposite trend holds for coherence, thereby highlighting the necessity of tailoring quantum resources to particle species and state structures in relativistic quantum information tasks.

Scalarization of charged Taub-NUT black hole and the entropy bound

This paper demonstrates that charged Taub-NUT black holes in Einstein-Maxwell-scalar-Gauss-Bonnet gravity undergo spontaneous scalarization, leading to a new branch of hairy solutions that possess strictly higher entropy than their scalar-free counterparts and exhibit a universal local entropy maximum at the bifurcation point.

Exact pp-wave solutions in shift-symmetric higher-order scalar-tensor theories

This paper demonstrates that shift-symmetric quadratic-order higher-order scalar-tensor theories admit exact, fully nonlinear pp-wave solutions, including "stealth" configurations where a nontrivial scalar field coexists with gravitational waves without altering the spacetime geometry, while also analyzing their behavior under disformal transformations and their compatibility with observational constraints.

Thermodynamics of Kerr-Bertotti-Robinson black hole

This paper resolves the ambiguity in defining the conserved mass of the Kerr-Bertotti-Robinson black hole by adopting the Christodoulou-Ruffini mass relation as a thermodynamic definition, thereby successfully constructing thermodynamic potentials that satisfy both the first law and the Smarr formula.

Analytic Expressions for Quasinormal Modes of a Regular Black Hole Sourced by a Dehnen-Type Halo

This paper derives compact and accurate analytic expressions for the gravitational quasinormal modes of a regular black hole embedded in a Dehnen-type dark-matter halo, revealing that the axial perturbations split into non-isospectral "up" and "down" channels beyond the eikonal regime.

Observational Signatures of Rotating Ayón-Beato-García Black Holes: Shadows, Accretion Disks and Images

This study investigates the observational signatures of rotating Ayón-Beato-García black holes, revealing how their mass, spin, and electric charge influence shadow morphology and accretion disk images, and ultimately constrains the electric charge parameter to a specific range consistent with Event Horizon Telescope observations of M87* and Sgr A*.

Revisiting $f(T)$ Teleparallel Gravity with a Parametrized Hubble Parameter and Observational Constraints

This paper investigates the accelerated expansion of the universe within $f(T)$ teleparallel gravity by proposing two cosmological models based on a parametrized Hubble parameter, which are then constrained and analyzed using Bayesian statistics on cosmic chronometer and Pantheon datasets to evaluate their expansion history, cosmological parameters, energy conditions, and the current age of the universe.

GWTC-4.0: Tests of General Relativity. I. Overview and General Tests

This paper presents the first of a three-part series detailing the overview, event selection, and general consistency tests of General Relativity using 91 confident gravitational-wave signals from the GWTC-4.0 catalog, finding no evidence for deviations from the theory in the dynamical and strong-field regime.

GWTC-4.0: Tests of General Relativity. II. Parameterized Tests

This paper presents parameterized tests of General Relativity using 91 confident gravitational-wave events from GWTC-4.0, finding no evidence for deviations from GR, spin-induced quadrupole anomalies, or line-of-sight acceleration, while significantly improving constraints on modified gravity theories and the graviton mass.

GWTC-4.0: Tests of General Relativity. III. Tests of the Remnants

This paper presents seven tests of the remnants from 42 confident gravitational-wave events in GWTC-4.0, finding overall consistency with General Relativity and no evidence for post-merger echoes, while noting that apparent deviations in hierarchical analyses are likely attributable to statistical variance from the finite catalog size.
